About this position

RIKEN’s Center for Computational Science is recruiting one fixed-term Researcher/Postdoctoral-equivalent staff member for the Large-Scale Parallel Numerical Computation Technology Research Team in Kobe, Hyogo, Japan. The successful candidate will contribute to next-generation high-performance computing and computational science research associated with Fugaku, Fugaku NEXT, and future domestic and international supercomputers.

The research focuses on high-performance numerical linear algebra, mixed-precision computation, computational reproducibility, eigenvalue calculation, and the Ozaki scheme. Duties include modernizing and advancing the EigenExa eigenvalue calculation library, researching highly reliable numerical linear algebra based on reproducibility, and implementing and optimizing numerical computation libraries for future HPC hardware. Applicants with strong interest in hardware-oriented co-design and emerging computing architectures are encouraged to apply.

A doctoral degree in a relevant field is required. Applicants should have knowledge of numerical linear algebra, precision analysis, or precision assurance, as well as C/C++ programming and parallel programming experience using MPI, OpenMP, or comparable technologies. English communication skills and the ability to work cooperatively with collaborators are also required.

The position offers annual income from ¥6 million, with fixed and variable salary components, discretionary work, commuting, and housing allowances, plus social insurance. The contract begins on or after April 1, 2027, by consultation, and may be renewed following evaluation up to a maximum of seven years.
